Summary of the invention

The present invention provides a kind of production method of label.The production method of label of the present invention, by following technical proposals come Realize: (1) then cured, oil removing, cleaning, drying are gone in the 2400 revs/min of buffing in plate front；(2) in yellow light or feux rouges Lower 200 mesh silk screen full versions are printed, and print burnishing surface for the first time, and 100 DEG C are dried 15 minutes, second of back up, then dry 30 with 100 DEG C Minute, it is tack-free to be cooled to surface；(3) time for exposure 20-100 seconds, developed with 3-5% aqueous sodium carbonate, water temperature is 50 DEG C, after the bubble several seconds, gently aqueous solution is brushed with soft wool brush, then clear water rinsing is secondary dries；(4) electrolysis method is lost It carves: electric current 15-50A, voltage 3-5V, electrolyte: 20% ammonium chloride, 20% potassium chloride, 20% sulfuric acid, anode titanium plate；(5) it loses The copper sheet that finishes is carved to be placed on water, sodium hydroxide, be heated up to 70 DEG C of membrane removals in 30: 1: 0.1 solution of potassium cyanide, wash out light.

The photosensitive etching of wire mark is completely combined with electroplating technology, can not only be produced by the production method of label of the present invention More exquisite label out, more magnificent medal, moreover it is possible to produce varied daily necessities, gift, craftwork.

Specific embodiment

Below by specific embodiment, the present invention is further illustrated.

Basic operation is as follows: 1.1 patterns and the film make because the product finely etched has entered the scope of the art work, So moulding, layout, color, the especially factor of many artistic effects such as light reflection and production technology should be permitted when drawing Perhaps condition is intact to be combined.The extra fine wire item of hollow out product should be at 1.2 times or more of base material thickness；Surface etching products Extra fine wire item interval should in 0.16mm or so, this in 0.16mm black line and it is white ground ratio can be made depending on reflectance difference 1:3,2:2,2:1.The positive and negative film surrounding of two-sided etching products should have clear and accurate alignment cross hairs, and positive and negative two pieces It will the nearly substrate of medicine film note.

1.2 plates handle the 2400 revs/min of buffing in (by taking copper sheet as an example) plate front, reach mirror effect, then Go cured, oil removing, cleaning, dried for standby.

1.3 wire mark photo-imaging photoresists are because pattern-making is superfine.It can not be repaired after development, therefore selected sense Optical cement is particularly important.My company selects the anti-corrosion ink of Gao Shi (coates) photo-imaging, with 200 mesh silk screens under yellow light or feux rouges Full version printing prints burnishing surface for the first time, and 100 DEG C are dried 15 minutes, second of back up, then are dried 30 minutes with 100 DEG C, to be cooled, Surface is tack-free, can be exposed.

1.4 exposing the exposure of air-breathing smile version machine.Time for exposure 20-100 second is differed, and lines are thinner, and the time for exposure is longer, instead It is then short.

1.5 developments are developed with 3-5% aqueous sodium carbonate, and water temperature is after 50 DEG C or so, the bubble several seconds, with soft wool Brush gently brushes aqueous solution, and then clear water rinsing is secondary, until reaching absolutely not removing residual glue.Wet copper sheet is directly lost It carves, row etching again after can also drying.

1.6 etchings can be etched with two methods: A, electrolysis method: electric current 15-50A, voltage 3-5V, electrolyte: 20% ammonium chloride, 20% potassium chloride, 20% sulfuric acid, anode titanium plate.Remove anode floating in electrolytic process in time and stays cathode copper, with Guarantee electric current normal through.B, tri-chlorination iron processes: purer ferric trichloride is selected to soak 30 Podbielniak degree solution, Flow Corrosion.Together One space of a whole page will reach depth different-effect, be after reaching either shallow for the first time and requiring, clean the surface, drying.It is shallow having reached Common etch resistant ink, then row second etch are coated and (stamped) at degree etching.1.7 membrane removals are placed on the copper sheet finished has been etched Water, sodium hydroxide are heated up to 70 DEG C of membrane removals in 30: 1: 0.1 solution of potassium cyanide, wash out light.Copper sheet after 1.8 plating membrane removals Pattern is very bright, very carefully, plates bright copper without row again, can directly carry out nickel plating 40-90 seconds, then go gold-plated, silver-plated.2 wire marks It is to support two methods of coloring with electrophoresis using coloring in by hand that production coloring, which is electroplated, in colored plating in the past.It colors in by hand, speed is slow, essence It is poor to spend, and is easy to the finish in damage non-staining face.Electrophoresis colour: (1) will have special equipment, and (2) will have certain batch, (3) it is limited by colored paint color dullness.Wire mark colored plating is exactly the pattern that will need to paint and text screen printing method will be various Color is imprinted on the metal plate for needing to be electroplated.Then row plating again, satisfactorily solves the defect of both the above method.Substrate is thrown --- wire mark, which is painted (red ink paste used for seals baking color), --- finally dries 150 DEG C of -1.5 hours --- nickel plating --- gold-plated (silver) nets for light cleaning Print colored plating process flow are as follows: concrete operations are as follows:

2.1 cleaning substrates note: A: before substrate is from polishing, cleaning and then from taking out in water to drying has been printed, overall process will wear hand Set operation, absolutely cannot directly be contacted with hand.B, it is all hydrophilic will to reach surface for substrate polished and cleaned, does not have any spot after air-drying Line.

2.2 make wire mark version is made a plate with 300 mesh terylene silk nets, and gap bridge will be got well, and residue glue will be washed down thoroughly and without trachoma With broken string.2.3, which choose screen printing ink, selects acidproof, alkaline-resisting, heatproof, the metal mesh printing ink of strong covering power, and our company selects day This Seiko 1300# ink.

2.4 fine wire marks, which are thoroughly dried, selects relatively low glue in hardness to scrape multiple black wire mark, and it is thick and uniform to reach layer of ink, does not have Broken string and trachoma, have printed baking (100 DEG C, 10 minutes) of the same colour of the same colour, have been printed for the last time in 150 DEG C, 1.5 hours of drying.

It to be placed in room temperature degreaser and (be heated up to 60 DEG C) soaking oil removing in 5-10 seconds after oil removing drying before 2.5 platings, then Whether cleaning checks without all hydrophilic at print.Not up to requirement, can be scrubbed with nylon brush, until reaching hydrophilic.

2.6 direct nickel plating, gold-plated (silver) usually plating are first copper facing, then gold-plated (silver), and copper-plated plating solution is pH value 0-1, nickel slot and golden slot pH value are 3.8-4.6.There are no the acid-proof inks that resistance to pH value is 0-1 in the world at present.(Seiko 3) it is so direct nickel plating, circumvents strong acid pass, increased with nickel, blast that it is pH value that 1300# ink is acidproof.Although speed slow one A bit, cost is higher, but high to value-added coefficient, and batch and little product, influences less.Electric current 30A when nickel plating, voltage 5V, movable cathode, increasing 0.3mm needs 18-20 minutes, needs to increase again, delay.(silver) gold-plated again after cleaning.
